Mackie SDR 24/96 faults
Hi all
Bought this second hand, very cheap in new condition, boxed. Apparently it never worked from new.

Well, I've completely dismantled the machine, checked the BIOS battery (3.2v) checked the continuity of all vales and re-assembled. On boot up, the machine usually shows the correct screen, but none of the buttons respond. All the power rails are correct. Very occassionally, the display shows the error message "innit fault (m) SDR halted. Does anyone know what this means please? Can't find it in any manuals. I have contacted the chap who is the guru on the other 2 models of Mackie recorders, but has no relevant info on this message, or indeed the SDR model
Oh yes, got to ask, could the operating system be corrupt, and where is it stored pleased? How do I re-format the had? Same as the dry and HDR?
I'm now re-reading the manuals to try and grasp fully how it works and how to do these things...I'm an old rust and plstic(audio tape) person unfortunately!
I'll shut up now


Do I need to re-install bios? Could this be a hd fault, and indeed, is any boot up info held on the hd?
I was told some boards from new we're faulty, I guess that could be it
I don't want to retire this machine, as I'm determined to fix it!

Many thanks for reading this, and I will update with anything that happens. I'm sure there are others out there that still want use there machines

Hi, I fixed one of these once, and that was a power supply issue. I know you say all PS voltages are correct, but sometimes if a cap goes bad, you can still read the correct voltages, but the supply doesn't have enough reserve to really make the machine work (gross oversimplification...). If you are comfortable and safe (with potentially lethal voltages inside) around HV electronics, you could take a look at the power supply and look for any capacitors that are either bulging or leaking. Even if you don't see those signs, it may still be a case of a cap simply drying up while in storage.
Best,
Ike
